l. '.'-P'.' MITH; BREAKbbwN GUN Filed Aug. 27, 1925 Patented Apr. 15, 1930 UNETED STATES LOUIS 1?. SMITH, OF ITHAGA, NEW YORK BREAKDOWN GUN Application filed. August 27, 1925. Serial No. 52,892.

This invention relates to improvements in break-down guns.

The primary object of the invention is to provide a barrel locking mechanism in combination with a safety mechanism position in dicator.

A further object of the invention is the provision of an operating mechanism common to both the barrel locking and the safety 19 mechanisms.

Other objects and advantages of the invention will be apparent during the course of the following description.

In the accompanying drawing forming a part of this specification and in which like numerals are employed to designate like parts throughout the same,

Figure 1 is a fragmentary side elevational view of the frame portion of a gun and shows assembled therein a barrel locking member, a safety mechanism operating button, and the manually operable means employed for actuating the barrel locking member and the said button in unison,

Figure 2 is a front end elevational view of the barrel locking bolt,

Figure 3 is a side elevational view of the barrel locking bolt,

Figure 4 is a rear end elevational view of the said bolt,

' Figure 5 is a vertical sectional view of the bolt, Figure 6 is a side elevational view of the bolt taken on the opposite side to the showing disclosed in Fig. 3,

Figure 7 illustrates partly in plan view and partly in transverse section a yoke member and a post which are employed for actuating the bolt shown in Figs. 2 to 6 inclusive. and

Figure 8 is a partly planview and partly transverse sectional view of the post shown in Fig. 7 with the post actuating cap operatively associated therewith.

In the drawing, wherein for the purpose of illustration is shown a preferred embodiment of this invention, the numeral 5 designates the frame portion which has rotatably journaled therein the post 6 having flattened sides 7 This post is manually operated by the top lever 8 shown extending longitudinally of the top face of the frame .5. Fastened to the post 6 and flushly engaging the flattened sides 7 are the furcations 9 of a yoke member 10 by means of the screw, 11 having 5;; the cylindrically-shaped head portion 12'projectin'g laterally therefrom. This yoke 10 is provided with an arm 13 having a ball-shaped end: 14 which is received within the socket 15 of the barrel locking bolt 16. v I

This rotatable bolt 16 is formedwith a longitudinally extending slot 17 communicating; at its inner end with a circumferentially extending slot 18, as best illustrated in Figs. 1 and 3. The slots 17 and 18 form the arcuate locking portion 19 of the bolt.

The projecting, cylindrically-shaped head 12 of the screw 11 is engaged by the depend ing, hook-shaped arm 20 of the forked end 21 of the safety button operating rod 22. This rod 22 has connected to its rear end the depending portion 23 of the safety mecha nism operating button 24 which is slidably associated with the top tang 25 of the frame 5. This top tang 25 is provided with a recess 26 which is employed for receiving a danger signal, such as a contrasting coloring matter, preferably red.

It will now be seen that by moving the top lever 8 to the right of the gun frame 5, the so post 6 will be rotated for throwing the yoke 10 around in a counter-clockwise direction, when viewed from above, or to the left for causing its arm 13 to rotate the bolt 16. This rotation of the bolt 16 will cause the longi tudinally extending slot17 to be arranged or located upon the top side of the bolt 16 where- I by the apertured ear portion, not shown, of a barrel will be permitted to be withdrawn from the slot. This rotatable movement of the post 6 will cause the head 12 of the screw 11 to be moved for bodily shifting the rod 22 which will cause the safety mechanism operating button 24 to be shifted longitudinally of the top tang 5 for causing the button to overlie or conceal the danger signal recess 26. The failure to see this danger signal will indicate to the user of the gun that the safety mechanism is in its locking position.

For the purpose of returning the bolt 16 and the post 6 to the positions illustrated in Fig. 1, a cap 27 is provided and is s ring pressed by the coil spring 28 for provi ing means to return the post and bolt to their normal positions. The connection between the cap 27 and the post 6 includes a ball 29 carried by the threaded screw 30 which is received within a suitable opening extending transversely through the flattened portion of the post 6.

10 It is to be understood that the form of this invention herewith shown and described is to be taken as a preferred example of the same, and that various changes in the shape, size and arrangement of parts may be resorted to 4 without departing from the spirit of the invention or the scope of the subjoined claim.

Having thus described the invention, I claim A break down gun provided with safety mechanism and having a barrel locking bolt rotatable on the longitudinal axis of the gun, a bolt operating post journaled on a vertical axis, a yoke pivotally mounted on said post and having a projecting arm universally jointed to the barrel looking bolt, the pivot pin of said yoke being elongated and operatively connected to the safety mechanism.

In testimony whereof I atfix my signature.
